1. Preparing your Motorola Razr Droid

2. Power on your Wahoo Heart Rate Belt

  • The Wahoo Heart Rate Belt will be powered on automatically by wearing it at your body. It has no On/Off pin!

3. Go back to your Motorola Razr Droid

  • Go to “Settings” -> “Wireless & Networks” -> “Bluetooth Settings”
  • Press scan for devices
  • Select the belt out of list and click it
  • Start the nRF HRM (Heart Rate Monitor) Demo at you phone

Please be aware that this photo is a photo montage. As soon you move the Wahoo Heart Rate Belt away from your body the Bluetooth Smart transceiver will be powered off.

I assume that the upper mentioned steps are close the same for the Nordic nRF8001 evaluation kit. I got the nRF8001 development kit this weekend as well, but I can´t use it because my nRFgo motherboard I loaned to one of my customers for testing the ANT+ ICs of Nordic. The nRFgo motherboard is supporting several other Nordic ICs. Anyhow, sooner or later I will have a complete Bluetooth Smart evaluation kit at my office. I will keep you posted for sure.

If you have interest in an own Buetooth Smart (Bluetooth Low Energy)  solution then just drop an email to harald.naumann (at) gsm-modem.de

  1. I have a Motorola Razor Maxx and a Polar H7 0005CA which will not work together using the HRM demo android app. I get a message “Bluetooth Low Energy isn’t supported by your phone :(“.

  2. Just replace the Polar to a Wahoo Heart Rate Belt. Inside Polar is maybe not a chip of Nordic Semicondutor. I run the demo on my Razr and and ir talking to the evaluation kit of Nordic and to the belt of Wahoo.
